My Husband and I have Horrible communication problems?

I just need some advice, Me and my husband have been Married for about a year and together for almost 5. We have had a good marraige, when its good, its really good, but as soon as anything remotely gets a little serious or bad, he just turns into a completely different person. I am the kindd that needs to talk about any problems that arrise so that we can resolve them and make our marraige better, and of course, like any man he is not. But I feel he takes it to a whole nother level. Its really hard for me to not be able to resolve our issues at all, but I have really tried to work on it, and I have cut it down to only trying to talk about the serious things that really need to be talked about in a marraige, and only once or twice a month usually, but even then, with the serious and even non-serious issues. He just snaps into this total jerk, that completely loses his temper, he mocks me, he screams and cusses at me, he is very vendictive, and completley unreasonable. I try my hardest
